Chicago Blackhawks captain Jonathan Toews is out indefinitely as he deals with an undisclosed illness.

"This offseason, I've been experiencing symptoms that have left me feeling drained and lethargic," Toews said in a statement from the team. "I am working with doctors so I can better understand my condition.

"Until I can get my health back to a place where I feel I can perform at an elite level and help my team, I will not be joining the Blackhawks for training camp. I do not have a timetable for when I will rejoin the team. I am extremely disappointed, but it wouldn't be fair to myself or my teammates to attempt to play in my current condition."

The team announced that 22-year-old forward Alex Nylander underwent knee surgery Monday and will be sidelined four-to-six months.
